Who Should Buy a Muscle Building Supplement

A muscle building supplement is an ideal choice for those who are looking to maximize their gains from time spent at the gym. Because most supplements are designed specifically with men in mind, their ingredients will be different than what women need. There are targeted weight loss supplements specifically for women to help with their needs.

If you’re following a muscle-gaining exercise routine and eating a well-rounded diet, but you’re still unhappy with your results, talk to your doctor about taking additional supplements for muscle building.

Many muscle building supplements claim to improve protein synthesis, speed recovery, and normalize hormone levels for maximum gains, however, there is currently inconclusive or not enough research to necessarily support all claims.

Unlike illegal anabolic steroids, legal muscle building supplements can be safe, but always talk to your doctor before starting one.

If you want to also cut down on weight, you may want to cut back on sugar. Need help with that? Check out our post on How To Wean Off Sugar: A Complete Guide On How To Wean Yourself Off Sugar.

Important Features to Consider

Not all muscle building supplements are created equal. A muscle building supplement should be effective and safe. Here’s what to consider when evaluating the options in search of the best muscle building supplement for your needs:

• Type. Muscle building supplements are available in single ingredient formulas and blends. Single formulas have just one main ingredient, while blends contain a “stack” or mix of ingredients. Depending on your overall health, budget, and goals, you may prefer to go with one or the other.
• Format. Another important consideration when it comes to choosing the best muscle building supplement is the format. There are powders, bars, shakes, and capsules available, but all help achieve the same end result — increased muscle mass.
• Ingredients. Certain ingredients have shown to help with muscle building, including protein and creatine. ^{12 13 14 15 16} Other ingredients may provide benefits in muscle adaptation, recovery and exercise performance, but more research is needed: beta-alanine, L-Citrulline, BCAAs, D-aspartic acid, and L-Arginine. ^{17 18 19}
• Labels. Keep in mind that most over the counter muscle building supplements are not regulated by the FDA. This leaves the burden of ensuring safety on the consumer, so carefully check information of all ingredients of a supplement before purchasing. Also look into the reliability of the manufacturer before buying any supplement. Quality manufacturers should list all ingredients and have access to lab tests and studies that show their products are safe and effective.
• Price point. Finally, consider how much you are willing to spend on a muscle building supplement. Muscle building supplements vary in price from $20-$100/month or more.
